-The action can be passed a CloudFormation Stack `name` and a `template` file. It will create the Stack if it does not exist, or create a [Change Set](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-changesets.html) to update the Stack. The change set is executed by default. By setting `no-execute-changeset: "1"` the change set is not executed and can be viewed. An update fails by default when the Change Set is empty. Setting `no-fail-on-empty-changeset: "1"` will override this behavior and not throw an error.
